FUEL-FEED SYSTEM.

of Illinois, `haveinve'nted new and useful Improvements in Fuel-Feed Systems, of which-the following is a specification.

This invention relates to a Vfuel feed system for automobiles, for the supply of gaso- -30 lene or other hydrocarbon fuel employed to lthe driving motor.` F. The object of the invention is to provide means whereby the owner of the car, when l he desires to retire the car for the night or t; any determined period, may cut oli' the feed ofthe hydrocarbon from the main reservoir, in such manner thatv the flow cannot be restored except by him or a duly authorized person, leaving only sufficient hydrocarbon in the line of feed to run the car a determined distance, whereby the owner of the'car is assured that the car cannot be surreptitiously operated while itis in sup posed retirement. I f' The invention consists of the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which Figure 1 is a sectional view showing the vapplication of the invention to an automobile of the touring car type. Fig. 2 is a top Iplan view of certain parts shown in Fig.

. 1. Fig. 3 is a longitudinal section through the auxiliary supply tank on an enlarged .scale.. Figs. 4 and 5 are sectional views through', the cut-off valve, showing`l the same 1n open and closed position. Fig. 6- is a sectional elevation showing the application 0 of the invention to an automobile of the roadster type.

Referring to the drawings, 1 designates the main fuel supply tank, 2 the motor, and A '3 the carbureter of an automobile driving 5 apparatus, which parts may be mounted upon the vehicle in any desired or required manner.

In carrying my invention into practice, I provide an auxiliary reservoir or supply tank 4k arranged in the line of feed between the main supply tank 1 and carbureter 3, which tank 4 is of relatively smaller size than the tank 1 to contain only a sufficient charge' for supply of the' fuel to run the vehicle a determined distance.

The tank 4 is connected at its inlet end Specification of Letters Patent.

with the main,supply pipe by a suitable inlet pipe or connection 5, and is connected at its outlet or discharge end with the earbureter by a feed pipe 6, said inlet and feed pipes forming part of the flow connection between the main reservoir and the motor.

.Arranged in'the inlet pipe 5 is a cut-off or controlling valve 7, which valve is preferably of the tapered-plug type and provided with a passage 8 for opening communication between the main and' auxiliary tanks when said valve is in open position.

Communicating with the'passage 8 is a cross passage 9 adapted, when the valve is closed, to cut off the flow of hydrocarbon from the main tank to the supplementary tank, and to communicate with an air inlet 10 in the valve casing for the admission lof air to said auxiliary tank to compensate for the feed ofthe hydrocarbon therefrom.

The tank 4 may be secured in any suitable manner to the tank `1 or body of the vehicle. or in any desired position between the main tank and carbureter, and, when a carbureter is not employed, the lineof -feed may be directly from the auxiliary tank to the motor.

Fixed to the casing of the valve 7 orto sol some other suitable support is a bracket arm 11 provided with anv opening 12, and connected wit-h the valve plug is van arm or lever 13 having an opening 14 to register with the opening 12 when the valve is closed. The lever 13 is arranged in such position as to be conveniently operated to open and closev the valve 7. The openings 12 and 14 are of proper form to receive the hasp of a suitable lock 15 which is adapted to be opened by an arbitrary type of key carried by the owner of the vehiclep or other duly authorized person.

In practice, the main Ireservoir 1 may be of a size to hold any desired quantity of hydrocarbon, while the auxiliary tank 4 is of a size to hold a comparatively small quantity, suiiicient only to supply the motor to run the vehicle a limited distance. It will thus be understood that the owner ofthe car desiring to retire the car for the night or for any determined period may close the valve 7 and lock it in closed position, thus cutting 01T communication between the main supply tank and the motor, and permitting only of the feed to the motor of the restricted quantity of hydrocarbon contained in the auxiliary reservoir 4. This restricted quantity of hydrocarbon may be sufiicient to supretirement.

ply enough fuel for a trip to and from a garage, or to run the vehicle only a limited number of miles, so that upon retiring the car the owner can feel assured that thecar can only be run a limited distance and cannot be operated any considerable distance by an unauthorized person during its supposed It is, of course, to-be understood that the invention is not limited. to the particular construction, proportion or arrangementy of parts herein shown, as these .may be moditied within the scope of the appended claims, as circumstances may require. v

In Fig. 1 I have shown the application of the invention 'to' an automobile of the touring car type, wherein the tanks are arranged lin the compartment 16 beneath the seat and the tank 4 is secured to the underside of the tank-1, the lever and bracket arm projecting outwardly through 4a slot 17 in the front wall of said compartment, while in liig. 6 I have shown the application of the invention to an automobile of the roadster type, Wherein the tank 1 is supported upon the back of the car body, the tank 2 secured to the bottom of the car body and the bracket arm and lever disposed inrthe space beneath the main tank, -where they may be conveniently reached.

Having thus described the invention, what I claim as new is:

1. In an automobile fuel feed system, a motor, a mainy fuel reservoir, an auxiliary Y:fuel reservoir in the line of feed between the main fuel reservoir and the motor, a valve controlling communication between said reservoirs, said valve being adapted in its open position to permit How of fuel from one reservoir to the other and in closed pofuel reservoir in the line ofeed between;L the mam reservoir and motor, a 'valve"con' trolling communication -between said resevoirs, said valve being operative 1n one position to establish communication betweenf the reservoirs' and in another position to close communication between thereservolrs.-

and open communication betweemthe aux iliary reservoir and thejatmosphere, a lever for operating the'va-lve, and means for lock-- ing said lever to said stationary bracket member to hold the valve closed.

3. In an autom-aticfuehfeed system, fa, motor, a main fuel reservoir, an. auxllmry fuel reservoir the line of feed' between the main fuel reservoir and the motor, a valve i casing in the'line of feed between said reselg-` voirs,i said casing h-aving'an air inlet, valve in said vcasing provided with a passage adapted when in open position to establish V'colnmunication between thereservoirs and when in closed position to register with said air inlet and establish communication tween the atmosphere andthe auxiliary res'- ervoir, an operating member for adjustingf said valve, and means for locking said op'- erating member in valve-closing position.
